Component Readiness has found a regression in the following test:

The test details below are for the vsphere variant where the event looks like:

event happened 25 times, something is wrong: namespace/openshift-machine-config-operator hmsg/fc3d043c6a machineconfigpool/worker - reason/SetDesiredConfig (combined from similar events): Targeted node ci-op-l9gc3cnz-9315e-5jmrh-worker-0-k9pgh to MachineConfig: rendered-worker-c9c7d6031a174631350e46cc20161d2f (06:40:25Z) result=reject

There is another test details report for the AWS variant where the pattern seems a little different. Feel free to expand this bug if they are in fact related.
